Designed to eliminate a wide range of contaminants in environments where air safety and cleanliness are challenged, consumables including HEPA filters, pre-filters (such as poly and pleated filters), carbon filters, and bag filters, are key components for achieving effective air treatment. Other consumables, such as UVGI and Ionic Hydro Generator Bulbs, also require tracking and periodic replacement to ensure proper contaminant control. The equipment’s life, performance, treatment effectiveness, and worker safety all depend on the timely replacement of these consumable components.

A multi-stage filtration system for air purification is a comprehensive air cleaning setup that employs multiple filter stages, each with a specific function and efficiency level. Designed to progressively remove various types and sizes of airborne contaminants, these systems ensure thorough and effective air cleaning, providing improved indoor air quality.

Primary Filters

The main, or principal, filter in the machine.

HEPA Filters: High-efficiency particulate Air (HEPA) filters used in air purification and negative air machines come in various types and configurations for specific filtration.
Bag Filters: Fabric or synthetic filter bags are used to capture and remove large volumes of particulate matter from industrial gases or airflows.

Carbon Bank Filters: A filtration system that utilizes activated carbon to adsorb and remove contaminants, including odors, gases, and volatile organic compounds.

Primary Filter Housings: Encloses bag filters and some carbon bank filters in the primary filter cavity of a multi-stage air purification system.

Secondary Filters

Provides supplemental filtration and additional soundproofing, or protects the primary filter.

MERV-Rated Filters: A MERV (Minimum Efficiency Reporting Value) rated filter is used to trap larger airborne particles. The higher the MERV rating, the greater the filtration efficiency.

  • Non-Framed Poly Pad – Also known as a panel filter. Made of woven polyester featuring Dustlok® technology, designed to capture and trap airborne dust and particles and extend the life of the filter.
  • Framed Pleated Panel Filters – Designed with pleats or folds to increase the surface area for greater particle capture capacity, resulting in longer life.

Carbon Activated Filters: These filters utilize activated carbon, which helps adsorb odors, gases, and volatile organic compounds (VOCs).

  • Non-Framed Carbon Pad – Infused with activated carbon, featuring OdorGuard technology. Designed to neutralize odors and volatile organic compounds (VOCs)
  • Framed Pleated Carbon Filters – Consist of pleated activated carbon material enclosed in a frame to remove odors and VOCs. Pleats increase the surface area for greater chemical capture capacity resulting in longer life.


UVGI (Ultraviolet Germicidal Irradiation) Bulbs: Emit ultraviolet light that is effective at deactivating microorganisms like bacteria and viruses.
PHI (Photohydroionization) Generator Bulbs: Uses a combination of ultraviolet (UV) light and a catalyst to generate hydroperoxides and ions, to neutralize airborne contaminants.
